How A Sleep Center Diagnose Sleep Apnea
Fragmented sleep, loud snoring, debilitating daytime fatigue, low oxygen levels, missed work days, morning headaches and problems remembering and concentrating are among the symptoms of sleep apnea disorder, the most common sleep disorder.
According to estimates there are more than 18 million Americans suffer from the deadly disorder called sleep apnea.
One of the first steps is generally to undergo an overnight sleep evaluation, or “nocturnal polysomnogram.” It is commonly known as overnight sleep study at the sleep center.
Patients spend one night in a special laboratory or a bedroom hooked up to sophisticated computer equipment that monitors heart, lung and brain activity; breathing patterns; arm and leg movements; and blood oxygen levels. The room generally includes soft lighting; a comfortable bed; a quiet, calming atmosphere; television; and other amenities to help the patient sleep.
In some cases, a portable home monitoring device can also be used to track heart rate, blood oxygen level, airflow and breathing patterns. Unfortunately, however, it does not always provide the most effective readings. An overnight, in-center polysomnogram may still be needed.
